We propose an approximate Detailed Configuration Accounting (DCA) approach starting from the variational model of configurations in jellium.

A Turbulent Heliosheath Driven by the Rayleigh–Taylor Instability

http://large.stanford.edu/courses/2011/ph241/olson2/ WebInstability occurring when a heavy fluid is superposed on a lighter one was first studied by Lord Rayleigh in 1883. The nature of this instability does not change when the problem is posed as a lighter fluid accelerating against a heavier one. G I Taylor first investigated it in this latter sense. low income assisted living chicago
